利用一組圖片來實(shí)現(xiàn)動(dòng)畫效果膀估，這里在項(xiàng)目中需要一個(gè)LoadingView汁蝶，自定義了一個(gè)UIImageView伏钠，使用這個(gè)只需在需要的位置創(chuàng)建這個(gè)UIImageView即可状勤。在這把自定義UIImageView類全部代碼分享給大家

self.alpha = 1
}
}
func hiden() {
UIView.animateWithDuration(0.25, animations: {

}) { (bool) in
self.stopAnimating()
}
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
}
// 使用方法
indector = FMLoadingImageViw(frame: CGRect(x: 0, y: 0, w: indectorWith, h: indectorHeight))
self.addSubview(indector!)
// 使用SnapKit添加約束
indector?.snp_makeConstraints(closure: { (make) in
make.centerX.equalTo(self.snp_centerX)
make.centerY.equalTo(self.snp_centerY)
})
